Given numbers are 540,209,197,747
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 540,209,197,747 is 1845373860.
Find LCM of 540,209,197,747 with Prime Factorization
| 3 | 540, 209, 197, 747 |
| 3 | 180, 209, 197, 249 |
| 60, 209, 197, 83 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 60 x 209 x 197 x 83 = 1845373860
Therefore, the lowest common multiple of 540,209,197,747 is 1845373860.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
540 x 209 x 197 x 747 = 16608364740
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
209 : 1, 11, 19, 209
197 : 1, 197
747 : 1, 3, 9, 83, 249, 747
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 540,209,197,747, is 1.
Now, the common factors can be found like this.
540:2x 2x 3x 3x 3x 5
209:11x 19
197:197
747:3x 3x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 16608364740/(1x9)
LCM = 16608364740/9
LCM = 1845373860
Thus, we can understand that the LCM of 540,209,197,747 is 1845373860.
